Organosilicon chemistry. Part XV. Thermal reactions of trifluoro(1,1,2,2-tetrafluoroethyl)silane and silicon tetrafluoride with methoxotrimethylsilane, hexamethyldisilazane, and trimethylsilanol
Trifluoro (1,1,2,2-tetrafiuoroethyl) silane reacts thermally with methoxotrimethylsilane, hexamethyldisilazane, or trimethylsilanol, possibly via co-ordination of the silicon atom of the SiF3 group with the nitrogen or oxygen atom of the other reactant, to give fluorotrimethylsilane and trimethoxo (1,1,2,2-tetrafluoroethyl) silane, tar, or polymeric material possibly the silsesquioxane (CHF2·CF2·Si·O1.5)n, respectively. Silicon tetrafluoride under the same conditions similarly reacts with the disilazane or the methoxosilane to give fluorotrimethylsilane and 1,1,1-trifluoro-3,3,3-trimethyldisilazane or fluorotrimethoxosilane, respectively.
